「觀音幻化，南詔立國」的神話最早出現於〈南詔圖傳〉，其於流傳過程中不斷發展擴充，內容更加豐富化、戲劇化，其中「觀音七化」逐漸演變為「觀音十八化」。另外，明初有白文之《僰古通》（《白古通記》、《白古記》、《白史》）一書行世，康熙時「寂裕」譯撰成漢文，稱為《白國因由》，自〈南詔圖傳〉至《白國因由》的擴展中可發現，此故事內容被大量擴充演繹，且滇密與巫教彼此拉鋸現象愈加強烈，甚至更直接明顯被表達出「君權神授」觀念。又另一方面，〈南詔圖傳〉與《白國因由》兩個版本之間，還有明初的《白古通記》一書，在分析比較後發現《白古通記》之「觀音七化」內容，應較接近〈南詔圖傳〉， 並非「寂裕」所言「備載《僰古通》」，而《白國因由》所載內容經後人敷衍成份極大，內容充滿佛法神蹟氣氛，與雖染神話色彩但屬歷史記錄性的〈南詔圖傳〉已截然不同。
